Nicotinic cholinergic activation of magnocellular neurons of the hypothalamic paraventricular nucleus

, 2002
The aim of the present work was to determine whether paraventricular neurons possess functional acetylcholine nicotinic receptors. Using infrared videomicroscopy and differential interference contrast optics, we performed whole-cell recordings in ...

Mechanisms of Exercise Training in Ameliorating Cognitive Function in Patients With Depression: A Narrative Review of Molecular Targets and Clinical Prescriptions

European Journal of Sport Science, Volume 26, Issue 11, November 2026.
ABSTRACT Depression is frequently accompanied by core cognitive impairments, notably in executive function and memory. Although the ameliorative effects of exercise training have been widely corroborated, the evidence regarding its underlying mechanisms remains fragmented. To provide a comprehensive and integrated view, this review proposes a testable,

Extra-cellular dopamine increases in the paraventricular nucleus of male rats during sexual activity

, 2003
Dopamine and 3,4-dihydroxyphenylacetic acid (DOPAC) concentrations were measured in the dialysate obtained with vertical microdialysis probes implanted into the paraventricular nucleus of the hypothalamus of sexually potent male rats.

Alpha-synuclein expression in oxytocin neurons of young and old bovine brains

The Journal of Reproduction and Development
Understanding of central nervous system mechanisms underlying age-related infertility remains limited. Fibril α-synuclein, distinct from its monomeric form, is implicated in age-related diseases. Notably, fibril α-synuclein spreads among neurons,

Mapping Projectome Heterogeneity of Subiculum Neuron Cell Types

Hippocampus, Volume 36, Issue 6, November 2026.
ABSTRACT The subiculum (SUB) is the main output structure of the hippocampus, influencing diverse behaviors through its widespread cortical and subcortical connections. Our previous work creating the mouse Hippocampus Gene Expression Atlas (HGEA) identified four genetically distinct cellular layers across five columnar domains in the SUB, with gene ...

A Cilia–Centered Nicotinamide Adenine Dinucleotide (NAD+) Signaling Network Regulates Hypothalamic Lysosomal Homeostasis and Metabolic Aging

Aging Cell, Volume 25, Issue 11, November 2026.
Aging‐associated NAD+ depletion in hypothalamic neurons shortens primary cilia and disrupts CHMP4B trafficking to lysosomes during lysosomal stress, leading to impaired TRPML1–mediated Ca2+ signaling and lysosomal stress responses. Calorie restriction restores hypothalamic NAD+ levels, ciliary structure, and lysosomal homeostasis, thereby improving ...

Dynamism of chemoarchitecture in the hypothalamic paraventricular nucleus

, 1988
The hypothalamic paraventricular nucleus (PVN) has been implicated in a remarkable number of functions including control of pituitary-adrenocortical activity in response to stress, body fluid homeostasis, milk ejection reflex, prolactin secretion ...

Voluntary exercise mitigates the effects of peri‐adolescent social isolation on emotion recognition and the oxytocinergic system in male mice

Journal of Neuroendocrinology, Volume 38, Issue 11, November 2026.
Abstract Social isolation, particularly during adolescence, is known to affect cognitive, emotional, and social behaviors as well as brain modulatory systems such as the hypothalamic oxytocinergic system. Interestingly, recent evidence indicates that exercise can exert beneficial effects on behaviors through the activation of the oxytocinergic system ...
